Hi,
it depends on your site survey.
Usually, a good recommendation is a minimum Bitate set to 12 Mbit/s for 2,4G and 5G.
Power Transmit Power for 2,4G should be between 8 and 14 dBm.
Power Transmit Power for 5G should be between 11 and 17 dbm.
Give it a try, but think about your Site Survey (e.g. with Ekahau AI Pro and Sidekick)
